AI agents call delete_issue to permanently remove resources in Redmine MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes an issue, which cannot be undone. Permanent deletion is irreversible and falls under the Destructive category. The severity is high because deleting issues could affect project tracking, audit trails, and historical records. While not a financial impact, the blast radius is substantial if an AI agent mistakenly deletes critical issues.
From the tool's definition Tool name is 'delete_issue' and description states 'Delete an issue permanently.' The word 'permanently' indicates irreversible data deletion.
Documented attack patterns abuse exactly the kind of access delete_issue gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Redmine MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_issue:
{
"version": "1",
"default": "deny",
"hide": [
"delete_issue"
]
}delete_issue disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
